A CPW Fed Hexagonal Patch Frequency Reconfigurable Antenna For Multiple Applications

This manuscript incorporates a coplanar waveguide fed a simple low-profile antenna to achieve frequency reconfigurability. The proposed structure in the PIN diode is attached in between the hexagonal patch and the rectangular slot. The Proposed frequency reconfigurable antenna structure provided frequency variations as the PIN Diode is switched. The resonating frequencies are 5.61 GHz, 9.59 GHz as PIN Diode is on, 6.74 GHz, 11.20 GHz, and 14.83 GHz as the PIN diode is off, providing maximum gain up to 7.73 dBi. This multiple-frequency variation of the antenna enables the antenna to use for multiple applications.
